After looking at all CA SSO configuration yielded no results; started looking at Apache and Proxy configuration. Here it was found that /siteminderagent* was defined within the proxy configuration. This was the root cause for Apache not being able to serve the content off its ALIAS mapping & very rightly so was being printed in WebAgentTrace log. After removing the entry for /siteminderagent* from Proxy Configuration the login.fcc worked fine.
